Jeff, I'd like to hear a little more about how and why you switched
ECMs.  I also have a V8 S-10 w/6965 ECM.  No lift kit, though.  The
motor is a stock 350 from a '91 Caprice.  Bruce said I should switch to
the 747, but it's my daily driver and I need a good reason to take it
down for a few days to make the switch.  What was your reason, and how
much was involved?  Has it affected your mileage?
